French authorities investigate major cyberattack on national tax service

French prosecutors have launched an investigation following a series of cyberattacks targeting the country's tax administration, the Directorate General of Public Finances (DGFiP). The security breach compromised personal and financial records belonging to nearly 700,000 individuals and commercial entities.

According to officials, the stolen information includes reference tax incomes, withholding tax rates, family quotient figures, land registry records, and inheritance files. Corporate data, such as company registration details and business addresses, was also accessed. The intrusions occurred across multiple incidents in recent months, prompting government crisis discussions and official notifications to affected taxpayers. Authorities have reiterated that the incident did not compromise core banking credentials, though investigations remain underway to identify the perpetrators and evaluate the full scope of the breach.
